for a sec i thought my kid was calling me :D hahah

I'd want to do that in order to stagger i/o across various hardware

[damoos]

You can but you only the smallest drives size will be available to the zpool. i.e. 1.5 + 1 = 1

Look up Raid6

Zfs can work with files, never mind hardware.

You can create an empty file, and then create a pool out of that file.

If, why would you want to do that ? But you can.. :-)

[proxicate]

does Raid-Zx have any advantages over raid 0,1 and 10?

[proxicate]

Does ZFS only work with raw hardware devices and basically take them over or can it just work with a partial allocation of a drive such as software raid on linux?

I am curious. I know somebody mentioned this before but I want to know if I can add different size HDDs to the ZFS.I have two 1 TB drives but I am getting a deal on 1.5 TB drive.

That would be a mirror vdev then?

If one drive fails (your pool will be "degraded" but still 100%online) you just replace it with a new drive and "resilver".

If your drives are hot-swap the pool will never go offline, if it's not your pool will only be offline during shut-down/replacement.

It will be online during resilvering.

The more I listen to this guy, he mentions allot of raid options you can use. That is 100% incorrect... you don't use traditional raid with ZFS. You use storage pools with multiple parity drives.
